2.4.4 CHIPSET
The chipset is designed to compliment the processor and provide the central point for the system’s
data transactions. The Compaq iPAQ 1.0/1.2 system employs the Intel 810E while the iPAQ 2.0
system uses the Intel 815E chipset.
The chipset is composed of a graphics memory controller hub (GMCH), an I/O controller hub
(ICH), and a firmware hub (FWH). Table 2-3 shows a listing of the functions provided by the two
types of chipsets.
